Here’s an example xorg.conf which works with X-out on a PVR-350 with a PAL TV
Install the ivtv driver as described here http://www.willmer.com/kb/2005/02/installing-ivtv-driver-for-pvr-350-card/
Then, following the instructions in utils/README.X11, install -c -m 0444 ivtvdev_drv_o /usr/X11R6/lib/modules/drivers/ivtvdev_drv.o
Then, set your default kernel to use a frame buffer.
Add vga=791 to your kernel line
Add this to the line starting # kopt… in /boot/grub/menu.lst vga=791
Identify the PCD ID of the PVR-350 card. lspci and look for the line relating to the PVR card.
